Over on CAPS, 393 of the 413 All-Star members who have rated Walgreen -- some 95% -- believe the stock will outperform the S&P 500 going forward. These All-Star bulls include joeGuitar and mm20001, both of whom are ranked in the top 10% of our community.

In February 2007, joeGuitar shared some firsthand experiences with our community: "Every [Walgreen] I've gone to is well-run. ... Aging population, more meds, well-run company, very good service, and innovative.... Go [Walgreen]!"

A pitch from mm20001 just two weeks ago shared that bullish optimism, breaking down the stock's seemingly cheapish valuation:

Despite the fact that Walgreen's has grown earnings at an amazingly steady 15% annual rate for the last 8 years (and longer), the stock is actually cheaper today than it was 8 years ago. The stock price certainly got ahead of itself in the late 90s and going into the 21st century with a high 45 P/E in Aug 2000, but has now come down to a reasonable P/E of 16 for the 12 trailing months. Add in the little debt on their books (as compared to CVS (NYSE:CVS), for example), and 5yr growth estimates of 14%, Walgreen's is a long-term buy today.
